An e-mail from a list of which I'm a member alerted me to the coat of arms of Sir Christopher Frayling, British writer on popular culture, who's particularly well known for his study of the so-called "spaghetti westerns" of Sergio Leone, and similar movies. That led to an interesting discussion with the College of Arms, as Wikipedia reports:
In 2001, he was awarded a knighthood for "Services to Art and Design Education" and chose as his motto "PERGE SCELUS MIHI DIEM PERFICIAS", which can be translated as "Proceed, varlet, and let the day be rendered perfect for my benefit". That is, 'Go ahead, punk, make my day'.
I giggled when I read that, and looked up his coat of arms to confirm it. Sure enough:
I'm sure Clint Eastwood approves!
